Rexroth R162211220 Linear Bearing Block
Bosch Rexroth’s R162211220 linear bearing block combines German engineering excellence with ISO 14728 compliance, delivering exceptional load capacity (C0=12,700N/2,856lb) and ultra-low friction coefficient (μ=0.002-0.003). This C1 preload-class linear motion carriage features 4-way equal load distribution and corrosion-resistant carbon steel construction, making it ideal for precision automation systems requiring moment stiffness up to 120Nm (88.5lb-ft).
